Abstract
The utility model provides a component device of a medical instrument, particularly a near infrared lens which is suitable for a mammary gland diagnose instrument. The near infrared lens which is suitable for a mammary gland diagnose instrument comprises a C-shaped threaded interface, a case body, a lens assembly, an infrared lens sheet and a pressing ring. The utility model has the great advantage that near infrared light is emitted after visible light passing through the lens. Thereby, the mammary gland diagnose instrument is operated in a near infrared region. The utility model which can be widely used for mammary gland general survey instruments is suitable for a bright environment. Convenience is brought to patients and doctors.
Description
This utility model relates to a kind of part device of Medical Instruments, especially a kind of near-infrared camera lens that is applicable in the mammary diagnosis instrument.
Existing mammary diagnosis instrument, technical maturity is widely used.But a defective is arranged, and because of its light source is a visible light source, video camera also is the television camera to the visible light sensitivity, and the spectral energy of its utilization that relies on mainly is in the visible region rather than in the zone of infrared or near infrared light.Therefore it must be patient (most of aeg of being) diagnosis in the darkroom, need squeeze breast repeatedly during owing to diagnosis, so all make troubles for doctor's (major part is the male) and patient.
This utility model purpose provides the near-infrared camera lens in a kind of mammary diagnosis instrument, and it can make the gamma camera in the mammary diagnosis instrument receive only near infrared light, thereby makes diagnostic apparatus be operated in bright environment.
In order to achieve the above object, this utility model is the selection standard camera lens at first, designs an Infrared Lens sheet as requested again, and its lens is oblate cylinder, leave a fixed gap between it and the battery of lens, its transmissison characteristic is only to allow the above infrared light of 800nm pass through.Designing the camera lens trim ring at last, is the hole in the middle of it, allows light enter video camera.
This utility model advantage is that it only can make near infrared light enter video camera, thereby makes mammary diagnosis instrument be operated near infrared region.
Figure of description is this utility model structural representation.Number in the figure (1) is a C type hickey, and (2) are housing, and (3) are battery of lens, and (4) are the Infrared Lens sheet, and (5) are trim ring.
This utility model manufacturing process is: the selection standard camera lens, according to its bore Design and Machining Infrared Lens sheet (4), make trim ring (5) at last, with Infrared Lens sheet (4) housing (2) of packing into, and leave a fixed gap between the battery of lens, outside Infrared Lens sheet (4), screw in trim ring (5) at last.
Claims (1)
1, the near-infrared camera lens in a kind of mammary diagnosis instrument, it comprises C type hickey (1), housing (2), battery of lens (3), Infrared Lens sheet (4), trim ring (5), it is characterized in that: battery of lens (3) front is an Infrared Lens sheet (4), there is a fixed gap front and back, Infrared Lens sheet (4) front is a trim ring (5), middle perforate.
